A substance or agent that prevents or inhibits ketogenesis, the metabolic process of producing ketone bodies in the body.
From anti- (against) + ketogen (from keto-, relating to ketones, from Greek keton, a chemical compound + -gen, producing). This medical term developed as researchers studied ketone metabolism.
Antiketogens are relevant to people following keto diets—if you want to stay in ketosis where your body burns fat for fuel, you'd actually want to avoid antiketogens and eat things that promote ketogenesis instead.
